Introduction:Recently there has been a renewal of therapeutic tools for the treatment of lymphoid neoplasms to increase the antitumor efficacy and reduce the toxicity generated by conventional chemotherapies, which adds to the intrinsic immunological dysfunction of the disease itself. To date, few data are published about infection risk of these new drugs, and the need for infectious prophylaxis is unknown. The aim of the study is to analyze the infectious complications in patients with LPD treated with monoclonal antibodies (obinutuzumab, ofatumumab, brentuximab, nivolumab and pembrolizumab), BTK inhibitors (ibrutinib, acalabrutinib) and PI3K inhibitors (idelalisib). Methods: Multicenter retrospective study in patients with LPD treated with targeted therapies (single agents or combination) in 18 Hematology centers in Spain, from the time of their commercial availability to March 2020. Patients in clinical trials were excluded as well as patients with active infections at the beginning of treatment. Results:During the study period, 380 patients were included.Baseline characteristics of the entire cohort are shown in Table 1.Median follow-up was 17.3 months (range 0-103), the longest follow-up corresponding to CLL patients (24 months, range 0-98) and the shortest to LBCL (5 months, range 0-25). Median exposure to target drugs was 8 months (range 0-72).Ibrutinib was administered to 219 patients(1 FL, 147 CLL, 27 MCL, 10 DLBCL, 1 TL and 32 WM, 1 HL),Brentuximab to 49(31 HL, 14 TL and 4 DLBCL) andIdelalisibto 35 patients (16 affected by chronic lymphocytic leukemia - CLL, 15 FL and 1 DLBCL, 1 WM, 1MCL, 1HL).Obinutuzumabcombinations were used in 10 (6 CLL, 3 FL, 1 MCL) and 5 HL patients (of which 4/5 underwent previous BMT) receivedNivolumab. A total number of 237 infectious events occurred in 148/380 patients (38.9%), 39% of which were grade 3 and 54/148 (36.4%) experienced 2 or more infective episodes: of those 54, 21 (38%) had underwent 3 or more lines of therapy and 28 (51%) had hypogammaglobulinemia. Hospitalization was required in 59.2% events. A bacterial cause of infection was reported in 40% of cases, and viral in 16%, including 11/237 (4,6%) SARS-CoV-2 infection. Invasive fungal infection (IFI) occurred in 3.3% (8/237). Noteworthy, no case of PJP was identified. Lung was the most frequent site of infection in 24% of cases (57/237) while the upper respiratory tract was involved in 17% of events (41/237). Urinary tract infections were diagnosed in 10% (24/237). Other sites involved were skin and soft tissue 7%, gastrointestinal tract 5,4%, bloodstream infections 3% and catheter related infections 2,5%. Considering drugs individually, 86 patients that receivedIbrutinib(39.2 %)experienced a total of 137 infectious episodes: 30% bacterial, 19% viral, 5% fungal and 45% clinical and image-based infections; the 17(34.6%of those who received Brentuximab, experienced a total of 16 infectious episodes: 56% bacterial, 37.5% viral infections and one catheter-related sepsis. Of those who receivedIdelalisib,18 (51.4%)experienced a total of 28 episodes: 42% bacterial, 14% viral and 7% fungal. Four patients treated withObinutuzumabcombinations (40%) experienced one infection during treatment (25% bacterial and 75% viral). Only one patient treated withNivolumabexperienced more than three infections, he was also under corticosteroid treatment. Focusing on IFI (Table 2): 7/8 infections were identified in CLL patients, 6 out 7 being on ibrutinib treatment and 1/7 on Idelalisib.Aspergilluswas the fungus most frequently isolated. The targeted drug was discontinued temporarily in 4 patients and indefinitely in 3. Twenty three (6%) patients died due to infection in our series. Conclusions: 1. We identified 38.7% infections in our LPD patients treated with targeted drugs, with a median drug-exposure time of 8 months (range 0-72), with a non-negligible incidence of bacterial infections. 2. The highest rates of infection were found in patients treated with with Idelalisib and Ibrutinib (51.4% and 39.2% respectively). 3. IFI (3.3%) occurred with low frequency, mostly in CLL patients during ibrutinib treatment, leading to its temporal discontinuation in most of the cases. 4. No case of PJP was identified in our cohort. 5. An analysis to determine risk factors for infection and the optimal monitoring and prophylaxis for these patients is ongoing.

Background The oral anti-apoptotic B-cell lymphoma 2 protein inhibitor venetoclax has shown strong activity in R/R AML in controlled clinical trials, and recently impressive results in treatment-naïve AML elderly patients with acute myeloid leukemia. However, limited data are available in the real-life setting. Methods This is a multi-center (n=4), retrospective study involving patients with treatment-naïve or Relapsed/Refractory (R/R) AML treated with Venetoclax in combination with HMAs. Data were collected after anonymous aggregation, in accordance with GCP and Helsinky declaration. Adverse events (AEs) were graded according CTCAE v4.03. Survival is estimated with Kaplan-Meyer method. Results Forty-four patients have been prescribed Venetoclax from March 2018 to June 2019 and completed at least 1 course of venetoclax (range 1-8, median 2, IQR 2.0 - 4.0), being evaluable in this analysis. Patients's characteristics are summarized in Table 1. Five/44 (11.4%) patients had a low risk AML, 21/44 (47.7%) had an intermediate risk AML and 14/44 (31.8%) patients had a high risk AML, according to ELN 2017 risk stratification (4 patients had no available ELN risk at baseline). Six out of 44 (13.6%) patients received Venetoclax in combination with HMAs as first line of therapy, whereas 14/44 (31%) as first line rescue for resistant AML, 15/44 (34.1%) at first relapse, 9/44 (20.5%) for second or further R/R AML. Among R/R patients who received Venetoclax, 17/38 (44.7%) and 21/38 (55.2 %) had received chemotherapy or HMAs as induction therapy, respectively. Overall, Venetoclax was combined with azacitidine in 19/44 patients (43.2%), with decitabine in 19/44 patients (43.2%), with Low-dose of Cytarabine in 5/44 (11.4%), and was performed in monotherapy in 1/44 (2.3%) patient. Three out of 44 patients (6.8%) received a maximum dosage of 100 mg daily, 2/44 (4.5%) received 200 mg, 37/44 (84.1%) received 400mg and 2/44 (4.5%) received 600 mg. Fifteen out of 44 (34.1%) patients reduced the dosage of venetoclax for concomitant Azole administration. The median follow-up is 75.5 (IQR 45.2 - 178.5) days for patients who received upfront venetoclax therapy, while 143 (IQR 49.2 - 235.7) days for R/R patients. In the first-line setting, no patients reduced venetoclax dosage for concomitant adverse events; two neutropenia grade IV and two thrombocytopenia grade III have been documented. In the R/R setting, 14/38 (36.6%) patients reduced venetoclax dosage for concomitant adverse events. Specifically, we reported 22 adverse events, of which 10 were grade III-IV (5 neutropenia grade IV, 2 pancytopenia grade IV, 1 neutropenia grade III and 2 febrile neutropenia grade III). The overall CR rate is 16.7 % in newly-onset AML patients and 28.9 % in R/R patients, respectively. Two out of 6 treatment-naive patients had an evaluable response at 2 months after the beginning of Venetoclax treatment, and 2/6 had an evaluable 4-months response: 1 stable disease (SD) and 1 disease progression (PD) at 2 months,1 SD e 1 complete remission (CR )at 4 months. Thirty-one out of 38 R/R patients had an evaluable response at 2 months and 21/38 had an evaluable 4-month response: 10 CR, 1 complete response with incomplete hematologic recovery (CRi), 14 SD and 6 PD at 2 months; 6 CR, 10 SD and 3 PD at 4 months have been documented. After a short follow-up period (75.5 days), no patients who received Venetoclax as upfront therapy underwent an allogeneic hematopoietic stem cell transplantation (HSCT). On the other hand, after a longer follow-up period (143 days), 5 out of 38 patients (13.2%) received a HSCT after Venetoclax therapy among R/R patients. Median Overall Survival was not reached in the newly-onset cohort. In R/R setting, median OS was 253 days (95% C.I. 157-349). Interpretation These data extend to the real-life setting some previous evidence obtained from trials. In particular, our data confirm that venetoclax plus HMAs or LDAC has an acceptable toxicity profile and is safe and manageable. However, especially in the R/R setting, hematological toxicity represents the most frequent adverse event, arising some concerns about the optimal drugs management. Although our data suggest a similar clinical activity of venetoclax combinations to that reported in clinical trials, further studies from the real-life setting are highly warranted to confirm venetoclax efficacy under normal clinical practice.

Abstract INTRODUCTION The hypomethylating agents (HMAs), decitabine (DEC) and azacitidine (AZA), have made it possible to treat more elderly patients with acute myeloid leukemia (AML). Both HMAs have demonstrated efficacy in monotherapy and in combination with targeted therapies. However, there is little direct comparative data on AZA and DEC in first-line treatment, and we do not know which group of patients might benefit from each drug. Results of the full analysis set (FAS) were presented previously (Labrador J, et al. ASH 2020). Here, we report long-term clinical efficacy from prespecified patient subgroup analyses. METHODS We conducted a retrospective study to compare real-life clinical outcomes between AZA and DEC in patients with AML ineligible for intensive chemotherapy included in the PETHEMA registry, and analyzed clinical variables associated with response and overall survival (OS) between AZA and DEC. RESULTS A total of 626 patients were included for the FAS between 2006 and 2019. 487 (78%) received AZA and 139 (22%) received DEC. Baseline characteristics were comparable in both groups, except for the percentage of bone marrow blasts (44% vs. 34% in the DEC group compared to AZA, p=0.010). In the FAS, there was no difference in the CR, CR/CRi or ORR (CR/RCi + PR) rate: 18%, 20.5% and 32% with AZA vs. 23%, 25% and 39.5% with DEC (p=0.20, p=0.27 and p=0.12). In the subgroup analysis, DEC was associated with higher CR/CRi rate than AZA in patients with ECOG ≥ 2 (95% CI: 0.088 - 0.801), bone marrow blast count < 50% (95% CI: 0.293 - 0.965), secondary AML (95% CI: 0.223 - 0.918) and adverse cytogenetics (95% CI: 0.171 - 0.857) (Figure 1A). DEC was associated with higher ORR rate than AZA in patients with ECOG ≥ 2 (95% CI: 0.116 - 0.782), leukocytes < 10 x10 9/L (95% CI: 0.321 - 0.920) and bone marrow blasts < 50% (95% CI: 0.321 - 0.920) (Figure 1B) 120 days-mortality was 25.4% after AZA and 27.1% after DEC, p=0.70. Patients who did not achieve at least a PR had significantly higher 120-day mortality with both HMAs (OR 8.85 and 8.22 for AZA and DEC, respectively). In the subgroup analysis, patients with leukocytes ≥ 10 x10 9/L (95% CI: 1.069 - 4.157) and those with estimated glomerular filtration rate (eGFR) ≥ 45 mL/min/1.73m 2 (95% CI: 1.249 - 4.664) had higher 120-day mortality with DEC than with AZA (Figure 1C) With a median follow-up of 12 months, median OS was 10.4 months (95% CI: 9.2 - 11.7) for AZA vs. 8.8 months (95% CI: 6.7 - 11.0) for DEC (p = 0.455). The subgroup analysis revealed that patients ≥ 80 years (95%: CI 1.005 - 2.341), with leukocytes ≥ 10 x10 9/L (95% CI 1.039 - 2.062), platelet count <20 x10 9/L (95% CI: 1.150 - 3.422) and those with eGFR ≥ 45 mL/min/1.73m 2 (95% CI: 1.040 - 2.059) did benefit for treatment with AZA compared to DEC (Figure 1D). CONCLUSIONS Our study provides real-life data on the outcomes of AML patients treated with AZA compared to DEC in a large retrospective cohort with long-term follow-up. In addition, we identify for the first time some baseline characteristics that could benefit from AZA or DEC in terms of responses, 120-day mortality and OS. These findings could help us to choose the most appropriate HMA in monotherapy or for the development of new combinations. Figure 1 Figure 1.

INTRODUCTION Paroxysmal nocturnal hemoglobinuria (PNH) patients treated with eculizumab have an increased susceptibility to serious meningococcal infections. In the largest safety data set to date, representing >10 years of postmarketing pharmacovigilance surveillance of eculizumab for the treatment of PNH, the reported meningococcal infection rate was 0.24 per 100 patient-years (PY); cumulative exposure to eculizumab in PNH was 21,016 PY (Socié G, et al. Br J Haematol. 2019). To reduce infection risk, it is recommended that PNH patients receive meningococcal vaccination ≥2 weeks prior to the first dose of eculizumab; patients vaccinated <2 weeks prior to eculizumab initiation are treated with appropriate prophylactic antibiotics (P-Abx) until 2 weeks after vaccination. However, some patients may still experience meningococcal infections, as vaccination reduces but does not eliminate the risk of meningococcal infection; thus, some physicians use long-term P-Abx in addition to meningococcal vaccination to lower infection risk. The real-world use of P-Abx is not well characterized, and their effect on the incidence of meningococcal infection is unknown. The objective of this study was to assess meningococcal infection rates in PNH patients who received eculizumab with or without P-Abx. METHODS This was a cohort study consisting of eculizumab-treated PNH patients from the International PNH Registry (NCT01374360). Eligible patients received meningococcal vaccination within 6 months prior to or up to 1-month post-eculizumab initiation; had a known birth date, sex, enrollment date, and status of P-Abx use; and were evaluable for infection during the study period. To prospectively assess the rates of meningococcal infections, the start of the follow-up period was defined as the later of the registry enrollment date or eculizumab treatment start date and the end of the follow-up period was defined as the earlier of the last eculizumab treatment follow-up date or date of the first meningococcal infection (i.e., patients were censored when they developed the first meningococcal infection after registry enrollment). To compare the demographic and disease characteristics between patients who started P-Abx and those who did not (No P-Abx), data were summarized at the later of the eculizumab start date, P-Abx start date, or enrollment date for patients with P-Abx use or at the last eculizumab treatment follow-up for No P-Abx patients. Event rates and corresponding 95% CIs were calculated for meningococcal infections for patients with and those without P-Abx using Poisson regression with an offset for the log of the treatment duration. RESULTS As of January 8, 2019, 1,815 eculizumab-treated patients were enrolled in the International PNH Registry, of whom 1,231 met all inclusion criteria for this study. Of the eligible patients, 501 received P-Abx and 730 did not. For the P-Abx and No P-Abx groups, the mean age of PNH onset (37.3 vs 36.8 y, respectively) and mean age at eculizumab initiation (44.4 vs 43.1 y, respectively) were similar. P-Abx use was higher in Europe (76.6%) than in other regions (Table 1). Both P-Abx and No P-Abx groups had similar medical event histories; the mean duration of the study period was 4.3 years (SD, 2.28 years) for the P-Abx group and 3.8 years (SD, 2.48 years) for the No P-Abx group. The mean duration of P-Abx use during the study period was 0.4 years (SD, 1.01 years). The most commonly used P-Abx was penicillin (314 of 500 patients). In total, 7 patients (3 from the P-Abx group and 4 from the No P-Abx group) experienced a meningococcal infection during the study period. In these 7 patients, the mean time from meningococcal vaccination to eculizumab initiation was 0.7 months (SD, 0.23 months) for the P-Abx group and 2.4 months (SD, 1.20 months) for the No P-Abx group. The estimated rates of meningococcal infection per 100 PY were 0.1 (95% CI, 0.0-0.4) for the P-Abx group and 0.1 (95% CI, 0.1-0.4) for the No P-Abx group (Table 2). CONCLUSIONS Rates of meningococcal infection were consistent with previously reported rates and were similar in PNH patients who received eculizumab therapy with or without P-Abx. It is important to note the small number of meningococcal infections and the limited details of P-Abx use reported in the registry. Further work will assess if patients were on P-Abx at the time of infection, and what meningococcal serotypes were identified.

Abstract Introduction: The outcome of patients with acute myeloid leukemia (AML) secondary to myelodisplastic syndrome (MDS) or therapy-related (t-AML) receiving conventional treatment and allogeneic stem cell transplantation consolidation (HSCT) is poor. CPX-351 is a new drug composed by liposomal encapsulated cytarabine and daunorubicin, at a fixed molecular ratio of 5:1. It showed superior results, compared to standard 3+7 induction, in a phase III trial (Lancet et al, JCO 2018) in patients affected by t-AML or AML with myelodisplasia-related changes and it is now commercially available for secondary AML (sAML). We recently published results from CPX-351 Italian Named (Compassionate) Use Program (CUP) which enrolled 73 elderly sAML patients (Guolo et al, Blood Cancer J. 2020) showing that CPX-351 is an effective induction regimen for high risk AML patients treated with a curative aim. With a limited follow up, our data suggested the good activity and tolerability of CPX-351. Good quality remissions with acceptable toxicity in the majority of patients was achieved and CPX-351 increased the feasibility of HSCT in a poor risk AML cohort. Scarce data are available on long term outcome of high risk patients receiving CPX-351 in the real life setting. Here we report the results from the extended follow up analysis of the Italian CUP. Results: Seventy three patients were enrolled between December 2018 and June 2019 in a compassionate use program (CUP) in 33 Italian Hematology Centers. Data collection began on July 2019 and included 71/73 patients (97.2%), enrolled in 31 Centers. As previously reported, median age was 65.5 years (52-79). Sixty-two (88%) patients had at least one relevant comorbidity upon enrollment. Six patients (9%) presented with ECOG 3-4 upon enrollment. With a median follow up of 22 months, median overall survival (OS) was 13 months (21.2 - 22.8 95% IC). Two-years OS was 28.6% in the whole cohort. In order to confirm the positive impact of HSCT in first complete remission (CR) and the correlation with the other variables, a landmark model was applied, including only patients alive and in CR at day 90. In landmark analysis, HSCT performed in first CR after CPX-351 was the only significant predictor of longer survival: median OS was not reached for patients transplanted in first CR Vs 12 months for patients who did not undergo HSCT, p &lt; 0.05, Figure1). Two-year OS for patients who received HSCT was 57.6% vs 15.8% for patients who did not undergo HSCT. Conclusions: Results from the extended follow up of Italian CPX-351 CUP confirm the good activity CPX-351 in such a difficult cohort as sAML. Two-year OS for transplanted patients is high despite the high median age, the high frequency of severe comorbidities in this real life cohort of patients and the high frequency of high risk AML. On the contrary, non-transplanted patients show a poor outcome, thus confirming that CPX-351 induction as an optimal bridge to transplant induction therapy. Figure 1 Figure 1.

Background Either allogeneic hematopoietic stem cell transplantation (SCT) from HLA-matched sibling donor or immunosuppressive therapy (IST) has been recommended as one of the standard treatments for severe aplastic anemia (SAA). Regarding only 30% of chance finding HLA‐matched sibling donor, SCT from an alternative donor including unrelated (URD) or haplo-identical related donor (HAPLO) is considered to be a treatment option after failure to IST in patients who lack of a HLA-matched sibling donor. The aim of this study was to compare the outcomes of URD SCT and HAPLO SCT for SAA patients. Method Consecutive 152 adult patients with SAA who received first SCT between March 2002 and May 2018 were included: 73 of HLA-well-matched (8/8) URD (WM-URD), 34 of HLA-mismatched URD (MM-URD), and 45 of HAPLO. With the intention to have a follow-up period at least 1 year, data were analyzed at May 2019. A conditioning regimen with total body irradiation (TBI) and cyclophosphamide was used for URD-SCT, whereas that with TBI and fludarabine was administered for HAPLO-SCT (Lee et al, BBMT 2011;17:101, Park et al, BBMT 2017;23:1498, Lee et al, Am J Hematol 2018;93:1368). The combination of tacrolimus and methotrexate were used as graft-versus-host disease (GVHD) prophylaxis. Results The median follow-up was 53.4 (range, 0.2-174.1) months. The median age of URD and HAPLO cohort was 30 (range 18-59) and 34 (range 18-59) years, respectively. Except for one and three patients who failed respective a neutrophil and platelet engraftment, other patients achieved neutrophil and platelet engraftments with median 11 and 15 days for WM-URD, 13 and 16.5 days for MM-URD, and 12 and 14 days for HAPLO, respectively. The five-years overall survival (OS), failure-free survival (FFS), and cumulative incidences (CIs) of graft-failure and transplant-related mortality were similar among three groups: 88.3%, 85.5%, 2.7%, and 11.7% for WM-URD; 81.7%, 81.7%, 0%, and 18.3% for MM-URD, and 86.3%, 84.1%, 6.7%, and 9.2% for HAPLO. The 180-days CI of grade II-IV acute GVHD in WM-URD, MM-URD and HAPLO were 35.6%, 52.9%, and 28.9%, respectively; and moderate to severe chronic GVHD were 28.7%, 38.7% and 11.8% in respective cohort. The CI of grade II-IV acute GVHD and moderate to severe chronic GVHD were significantly higher in MM-URD than those in HAPLO (both, p=0.026). ATG is the only factor affecting both grade II-IV acute GVHD (Hazard ratio 0.511, p=0.01) and moderate to severe chronic GVHD (Hazard ratio 0.378, p=0.003) in multivariate analysis. Other complications including CMV DNAemia, hemorrhagic cystitis, invasive fungal disease, secondary malignancy, and sinusoidal obstruction syndrome were similar among three groups. Survival outcomes of a subgroup of ≥ 2 allele MM-URD (n=16) extracted form MM-URD were inferior that of other donor types (n=136): 75.0% vs. 86.9% (p=0.163) for 5-year OS and 75.0% vs. 84.7% (p=0.272) for 5-year FFS. Conclusion This study shows that there were no significant differences between alternative donor sources in the absence of suitable matched sibling donor. Host/donor features and urgency of transplant should drive physician towards the best choice among alternative donor sources for SAA patients treated with SCT. However, selection of ≥ 2 allele MM-URD should not be recommended due to high incidence of GVHD and inferior outcomes.

Introduction: About 2 to 10% of patients (pts) diagnosed with Chronic Lymphocytic Leukemia (CLL) develop diffuse large B-cell lymphoma (DLBCL, so-called Richter transformation (RT)) over long-term follow-up. The outcomes of pts with RT are variable and poorly understood and there is no consensus on the best therapeutic approach. The aim of this study was to analyze the clinical characteristics, outcomes and factors predictive of survival in a large series of RT from the French Innovative Leukemia Organization (FILO). Methods: Biopsy-confirmed RT (limited to DLBCL and excluding Hodgkin lymphoma) diagnosed from 2001 to 2018 were identified from eight FILO centers. Clinical and biological characteristics of CLL and RT at diagnosis, including cytogenetics, clonal relation with the pre-existing CLL, Epstein-Barr virus (EBV) status, cell of origin (COO) analyzed by immunohistochemistry and RT score (Tsimberidou AM et al, J Clin Oncol, 2006) were analyzed as well as treatment and outcomes. Overall survivals (OS) were defined as time from CLL and RT diagnosis to death from any cause and analyzed using the Kaplan-Meier method. Statistical analyses were performed with SAS version 9.4. Results: A total of 70 CLL pts who developed RT were identified. The median age at CLL diagnosis was 62 years old (range 35-82), and 50 (71.4 %) were male. The median time to transformation was 5.5 years (range 0 to 22 years), with 12 simultaneous diagnosis of CLL and RT. Prior to RT, 20 (29%) pts had not been treated for CLL, 50 received one (n=21) or more (n= 29) line of treatment ; 6 pts had received a novel agent (ibrutinib, idelalisib or venetoclax). The median age at RT diagnosis was 68 years old (range 42-88). All biopsies were centrally reviewed; 38/58 pts (66%) had elevated LDH (>1.5N) ; 35/65 pts (54 %) had bulky disease (≥ 5 cm); 10/54 (18.5%) pts had del(17p) or TP53 mutation ; 9/42 pts (21%) had a complex karyotype (at least 3 abnormalities). The CLL and RT were clonally related in 27/27 (100%) tested pts. COO by Hans algorithm was non germinal center B cell-like (GCB) in 26/28 pts (93%). EBV was positive or detected in 5/40 (12.5%) pts. The median of Ki67 positivity was 70% (range 30% to 100%). The RT score (based at RT diagnosis on ECOG performance status 2-4, LDH >1.5 x normal, platelets<100 x 109/L, tumor size >5 cm and >1 prior therapy for CLL) was : low risk in 17 pts (31%), low-intermediate risk in 10 pts (19%), high-intermediate risk in 14 pts (25%) and high risk in 14 pts (25%). The most common first-line treatment of RT was immunochemotherapy (n=57, 87%) including R-CHOP-like regimen (n=48, 73%). Autologous or allogeneic transplantation was performed for 7 pts (11%). Response to first-line treatment was complete or partial response in 26 pts (40%), and stable disease or progression in 39 pts (60%). After a median follow-up of 8 years, 51/64 pts (80%) have died. The main causes of death were progressive DLBCL (n=36, 71%), infection (n=8, 16%) or progressive CLL (n=2, 4%). The median OS of the cohort from CLL and RT diagnosis (Figure 1) were 7.8 years and 9.5 months, respectively. In univariate analysis, patients with TP53 disruption at CLL stage, low platelets count, elevated LDH, elevated beta2-microglobulin, high ECOG score, high RT score, EBV positivity and absence of response to first-line RT treatment had worse OS. The ECOG score, platelets count and TP53 disruption remain significant in multivariate Cox-regression. Last, we compared the clinical and biological parameters of two Richter groups defined as: (i) short-term survivors (<12 months, n = 34) and (ii) long-term survivors (>48 months, n = 18). Long survival was significantly associated with elevated platelets count, low LDH, low ECOG, low RT score and response to RT first-line treatment. Discussion: The clinical outcomes of RT patients is poor and novel treatment options are needed. However, a group of long-term survivors was identified, characterized by elevated platelets count, low LDH, low ECOG, low RT score and response to immunochemotherapy.

Abstract Introduction: The role of autologous hematopoietic stem cell transplantation (auto-HCT) in the management of patients with Waldenström Macroglobulinemia (WM), a rare, indolent lymphoma, has not been established. We had previously published our experience with auto-HCT in a small cohort of WM patients1. Here, we present an updated analysis of auto-HCT with a larger cohort of WM patients. Methods and study population: The study cohort was comprised of 29 patients who underwent high-dose chemotherapy and auto-HCT at MD Anderson Cancer Center (MDACC). The Kaplan-Meier method was used to create survival curves. Overall survival (OS) was defined as the duration from date of transplant to death or last date of follow-up in living patients. Progression-free survival (PFS) was defined as the duration from date of transplant to either progressive disease or death, whichever occurred first. Results: Median age at auto-HCT was 60 (range, 43-75 years). Eight patients (28%) had concurrent light chain amyloidosis (AL). Of the five patients who had MYD88 testing completed, 3 were positive for the MYD88 mutation. Additionally, of these 3 patients, 2 were also positive for CXCR4 mutation. Patients received a median of 2 lines (range 1-6) of therapy prior to auto-HCT; 3(10%) patients had primary refractory disease, 8(28%) were in first remission, and 18 (62%) had relapsed disease. Median time from transplant to last follow-up for the surviving patients was 5.3 years. Preparative regimens received by the patients were: Melphalan (n=20), BEAM-R (n=2), Busulfan/Melphalan (n=1), Cyclophosphomaide/Etoposide/total body irradiation (n=1), Thiotepa/Busulfan/Cyclophosphamide (n=1), and Carmustine/Thiotepa (n=1). Three patients further went on to receive allogeneic transplant either after relapse from auto-HCT or due to disease transformation to aggressive lymphoma. Twenty-eight patients achieved engraftment with a median time to neutrophil engraftment of 11 days (range, 10-15 days). One patient suffered primary graft failure due to progression of disease and died 84 days after transplant. Non-relapse mortality was 3.4% at 1 year. All patients were eligible for response evaluation. The median OS from diagnosis was 12.2 years. Overall response rate was 96%: complete response (n=8, 27.6%), very good partial response (n=5, 17.3%), partial response (n=15, 51.7%), and progressive disease (n=1, 3.4%). PFS and OS at 5 years were 43.3% and 62.9%, respectively. Median PFS and OS from auto-HCT were 4.1 and 7.3 years (Fig. 1A). The median OS from auto-HCT in first remission + primary refractory and relapsed disease was 8.2 years and 4.1 years, respectively.16 patients were alive at the time of censoring while 13 patients had died. Causes of death include relapsed disease (n=6), secondary malignancy (n=2), infection (n=1), chronic graft-versus-host disease (n=1), and unknown (n=3). 8 patients (28%) were positive for concurrent AL amyloidosis. The sites of amyloid involvement were kidneys (n=2), lungs (n=1), bone marrow (n=1), heart(n=1), lymph nodes(n=1), gastrointestinal tract (n=1) and subcutaneous fat aspirate(n=5). The median overall survival for patients with amyloid involvement (n=8) was 12 years. On univariate analyses, the number of chemotherapy regimens prior to transplant (≤ 2 vs >2 lines) was the strongest predictor of overall survival (p=0.03, HR 0.3, CI: 0.09-0.9, log-rank) and PFS (p=0.001, HR 0.24, CI: 0.07-0.85, log-rank). The median PFS in patients with ≤ 2 lines and > 2 lines of therapy was 71 months versus 19 months, respectively (Fig. 1B). Conclusion: Auto-HCT is safe and feasible in selected patients with WM, with a high response rate and durable remission even in patients with relapsed or refractory disease.

Introduction: The R-MegaCHOEP trial showed that dose-escalation of conventional chemotherapy necessitating autologous stem cell transplantation (ASCT) does not confer a survival benefit for younger patients (pts) with high-risk aggressive B-cell lymphoma in the Rituximab era (Schmitz et al., Lancet Oncology 2012; 13, 1250-1259). To describe efficacy and toxicity over time and document the long-term risks of relapse and secondary malignancy we present the 10-year follow-up of this study. Methods: In the randomized, prospective phase 3 trial R-MegaCHOEP younger pts aged 18-60 years with newly diagnosed, high-risk (aaIPI 2-3) aggressive B-cell lymphoma were assigned to 8 cycles of CHOEP (cyclophosphamide, doxorubcine, vincristine, etoposide, prednisone) or 4 cycles of dose-escalated high-dose therapy (HDT) necessitating repetitive ASCT both combined with Rituximab. Both arms were stratified according to aaIPI, bulky disease, and center. Primary endpoint was event-free survival (EFS). All analyses were calculated for the intention-to-treat population. This follow-up report includes molecular data based on immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) for MYC (IHC: 31/92 positive [40-100%], FISH: 14/103 positive), BCL2 (IHC: 65/89 positive [50-100%], FISH: 23/111 positive) and BCL6 (IHC: 52/86 positive [30-100%], FISH: 34/110 positive) and data on cell of origin (COO) classification according to the Lymph2CX assay (GCB: 53/88; ABC: 24/88; unclassified: 11/88). Results: 130 pts had been assigned to R-CHOEP and 132 to R-MegaCHOEP. DLBCL was the most common lymphoma subtype (~80%). 73% of pts scored an aaIPI of 2 and 27% an aaIPI of 3. 60% of pts had an initial lymphoma bulk and in 40% more than 1 extranodal site was involved. After a median observation time of 111 months, EFS at 10 years was 57% (95% CI 47-67%) in the R-CHOEP vs. 51% in the R-MegaCHOEP arm (42-61%) (hazard ratio 1.3, 95% CI 0.9-1.8, p=0.228), overall survival (OS) after 10 years was 72% (63-81%) vs. 66% (57-76%) respectively (p=0.249). With regard to molecular characterization, we were unable to detect a significant benefit for HDT/ASCT in any subgroup analyzed. In total, 16% of pts (30 pts) relapsed after having achieved a complete remission (CR). 23% of all relapses (7 pts) showed an indolent histology (follicular lymphoma grade 1-3a) and 6 of these pts survived long-term. In contrast, of 23 pts (77%) relapsing with aggressive DLBCL or unknown histology 18 pts died due to lymphoma or related therapy. The majority of relapses occurred during the first 3 years after randomization (median time: 22 months) while after 5 years we detected relapses only in 5 pts (3% of all 190 pts prior CR). 11% of pts were initially progressive (28 pts) among whom 71% (20 pts) died rapidly due to lymphoma. Interestingly, the remaining 29% (8 pts) showed a long-term survival after salvage therapy (+/- ASCT); only 1 pt received allogeneic transplantation. The frequency of secondary malignancies was very similar in both treatment arms (9% vs. 8%) despite the very high dose of etoposide (total 4g/m2)in the R-MegaCHOEP arm. We observed 2 cases of AML and 1 case of MDS per arm. In total 70 pts (28%) have died: 30 pts due to lymphoma (12%), 22 pts therapy-related (11 pts due to salvage therapy) (9%), 8 pts of secondary neoplasia (3%), 5 pts due to concomitant disease (2%) and 5 pts for unknown reasons. Conclusions: This 10-year long-term follow-up of the R-MegaCHOEP trial confirms the very encouraging outcome of young high-risk pts following conventional chemotherapy with R-CHOEP. High-dose therapy did not improve outcome in any subgroup analysis including molecular high-risk groups. Relapse rate was generally low. Pts with aggressive relapse showed a very poor long-term outcome while pts with indolent histology at relapse survived long-term. Secondary malignancies occurred; however, they were rare with no excess leukemias/MDS following treatment with very high doses of etoposide and other cytotoxic agents.

Introduction: The addition of gemtuzumab ozogamicin (GO) to 7+3 chemotherapy for newly diagnosed acute myeloid leukemia (AML) has been shown to significantly improve event-free survival (EFS) for cytogenetically favorable-risk AML, with marginal benefit for intermediate-risk AML, and no benefit for cytogenetically adverse-risk AML. Of note, with the exception of mutated FLT3-ITD, little is known about the impact of GO in ELN 2017-defined genotypically adverse-risk AML, and a recent randomized trial found no EFS benefit for 7+3+GO in patients (pts) with genotypically favorable-risk, NPM1-mutated AML. Since 2017, our institution incorporated GO into 7+3-based inductions for all "non-adverse" risk AML pts, as defined by wild-type FLT3 and no abnormalities on rapid FISH analysis for del(5q)/monosomy 5, del(7q)/monosomy 7, and del(20q). We report our experience treating all pts with "non-adverse" risk AML-as defined by this algorithm-with 7+3+GO. Methods: An institutional database was queried in order to identify all pts ≥18 years old who received 7+3-based chemotherapy for newly diagnosed AML between 2017 and 2020; pts who received the FDA-approved fractionated dose of GO were included in the analysis. Data collection included demographic variables, karyotype/FISH, targeted PCR analyses, and multigene NGS panels for AML-related mutations including, but not limited to, mutations in FLT3, NPM1, CEBPA, TP53, RUNX1, and ASXL1. Outcome data included response to induction, relapse, and death, as well as hematopoietic cell transplant (HCT) rates, conditioning regimens, and post-transplant complications. Results: Between January 2017 and July 2020, 96 pts received 7+3-based induction at our institution. Of these, 29 (30%) received 7+3 in combination with GO. Median age at diagnosis was 46 years (range 23-66), with 17 (59%) males. Sixteen (55%) pts had ELN favorable-risk AML (5 [31%] by cytogenetics and 11 [69%] by genotype), 6 (21%) pts had ELN intermediate-risk AML, and 7 (24%) pts had ELN adverse-risk AML (4 [57%] by cytogenetics and 3 [43%] by genotype). Median time from diagnosis to start of induction was 4 days (range 0-43). For cytogenetically adverse-risk pts, median time from diagnostic bone marrow biopsy to receipt of adverse karyotype results was 8 days (7-14). Median time from start of induction to receipt of multigene NGS results for all pts was 15 days (3-32). Overall, 22 (76%) pts achieved remission. All genotypically adverse-risk pts (1 with mutated TP53 and 2 with mutated RUNX1) were refractory to induction, while 3 of 4 (75%) cytogenetically adverse-risk pts (1 with t(6;9), 1 with monosomy 7, and 2 with 11q23 abnormalities) achieved remission. Eight of the 29 (28%) pts proceeded to HCT, including 4 adverse-risk pts. Of the adverse-risk pts, all received myeloablative conditioning prior to HCT and 3 (75%) developed veno-occlusive disease (VOD), with 2 (50%) requiring defibrotide therapy. In favorable/intermediate-risk pts, 4 (18%) proceeded to HCT (2 intermediate-risk pts in first remission and 2 favorable-risk pts in second remission). Of these, 2 (50%) received myeloablative conditioning and 1 (25%) developed VOD. At last follow-up, 23 of 29 pts (79%) remained alive, with a median overall survival not reached (range 1-29 months) and a median EFS of 20 months (9-31). The percentage of ELN favorable-, intermediate-, and adverse-risk pts who remained event-free at last follow-up was 75%, 33%, and 43%, respectively. Discussion: This single-center, retrospective cohort describes the outcomes of pts with "non-adverse" risk AML who received induction chemotherapy with 7+3+GO according to a pre-defined algorithm. Using this algorithm, 30% of all pts receiving 7+3-based inductions received GO. Of these, nearly 25% were ultimately found to have adverse-risk AML as defined by ELN 2017 criteria, largely driven by long turn-around times for karyotyping and NGS multigene panel results. No patient with genotypically adverse-risk AML by ELN criteria responded to induction chemotherapy, and 75% of cytogenetically adverse-risk pts who proceeded to HCT developed VOD. Routine use of 7+3+GO induction outside of the context of cytogenetically favorable-risk AML remains controversial, and further study is needed to define the role of GO, particularly for pts with ELN genotypically adverse-risk AML.

To assess the efficacy of radioimmunotherapy (RIT) with 90yttrium-ibrutinib-tiuxetan (90Y-IT) in mantle cell lymphoma, data from 90 patients registered in the RIT Network with a median follow-up (FU) of 5.5 years after RIT were evaluated. 90Y-IT was given as first-line therapy in 45 (50%) (consolidation 44 pts., primary therapy 1 pt.) and at relapse in 45 (50%) patients (consolidation 24 pts., recurrence 12 pts., therapy refractory 3 pts., conditioning 2 pts., other 4 pts.). As a first-line treatment, 30 patients (pts.) (67%) achieved CR, 10 pts. (22%) PR%., 1 pt. (2%) PD, and for 4 pts. (9%) no response data was available. At relapse, CR was achieved in 17 pts. (38%), PR in 6 pts. (13%), SD in 2 pts. (4%), and 6 pts. (13%) had PD, while the response was not documented for 14 pts. (31%). After a median FU of 5.5 years, median PFS for all patients was 2.11 (95%CI: 1.03-2.32) years, and median OS was 4.05 (95%CI 2.79-7.21) years. Eleven pts. (12.2%) developed second malignancy. In conclusion, this is the largest report of MCL pts. treated with 90Y-IT to date. 90Y-IT was most often used as consolidation after first- and second-line chemotherapy and may improve the results achieved using chemoimmunotherapy alone. However, the results are less encouraging compared to treatment with small molecules such as ibrutinib.
